Be it known that I, SINCLAIR J. JoHNsoN,-a citizen of the United Sta-tes, residing at Nut-fv ley, in the county of Essex and State of Newj' 5 Jersey, have invented certain new and useful Improvements in CarDoors,-of which the following isa specification. This invention-relates to doors, and 'espe--r cially to car-doors adapted for use with freight? Io boxfcars, the object of the invention being-to1 provide an improved car-door which in i'ts closed position will be flush with tl1e=door caseor wallof the ear and can bemoved into? its open position with facility and with-com' 1 I5 paratively-little labor and is, moreover, soE assembled with the car-'body that in use lit will not-get ont of workingvo'rder. i

' ISilnila-r characters vof reference designate like lparts inail the figures of 4the drawings. 65 'The present improvement -is designed to provide a car-door which in y"its closed @posiition will be flush with the door-case-or bodyiwall, the improvedoperating means of which iis effectiveto move said door -ina plurality 7o iof directions'from its 'iush position "into apo- :sition from which it'fcan @be vreadily moved fawayfrom the vdoorway.,v andfor Athis 'purpose .I have provided an improved structure-*comprising ina general wayfa door having one'or 75 rmore carriers and an actuator or actuating ime'anseiective to operate-the door'in'two di- ;rec'tions, either into position Hush with 'the' door-case orboiy-wallor from such position into position-to bemovd away from the door- 8o way; Aand the improvement Acomprises in `a `:general wayl a' door," af* carrier secured rto said idoor, -means for supporting said carrierfand iactuating means Sfor shifting `the door, and p which means is so organized that'the 'door 85 fwi'll 'have la parallel'amotionand will e'eetivel'y =lock fthe door in its vclosed position 'or 1in its open :position againstthe side of the car.

In 'the'forni 'thereof herein 'shown and described and .which may be its preferredform, 9o )if desired, the door2fmay comprise the usual' .structure ordinarily used in-freight box-'cars and of a size toii't `witll'iinthe doorway 3 fiush with the car-body 4.1., -Secured to-'such car- "body 4 above-thedo'or is a track 5, adapted to 95 support the door-carrier. Ths-trackmaybe @ofl such length that the "door may .be shifted Ithereon 4away from eitherside of the doorway, the f mechanism being organized to permit this,

1o'r such track may carry additional doors if Ioo found desirable. A n v `In one form thereof the door is 'provided {with apair of carriers, (designated in agencase and door shown in Fig. 5. Fig. e7 is aXA =eral way-'by:A,1)-eachfeomprising ahanger 6,

- fulcrum therefor, suchlevers being provided ject beyond the outer face of such door.

having suitable means-such, for instance, asa roll 7-for engaging the track, and so constructed that in working it will not be thrown therefrom, this object being secured by providing the hanger with'a downwardly and upwardly extending iiange 8 overlapping the inner side of the track. instance the hangers are located beyond the edges of the door, so that when the door is open the hangers may not appreciably pro- -Each hanger is soconstructed that'it is'in close engagement with the under edge of the track, so as to prevent play of such hanger relatively thereto. This feature combined with the construction of carrier hereinafter set forth permits the provision of a door having a steady parallel motion, so .that during its shifting movement there will be no swinging or vibratory movement.

Pivotally carried by each hanger, which acts as one member of a hinge for shiftable movement relatively thereto, is a pair of cranks 9 and 10, one below and in parallelism with the other. These cranks are secured to the door by a suitable plate 12, having bearings 13, into which the ends of the cranks extend, being fixed against separation there from by some suitable means, such as pins 14, such plate thus constituting the other memv ber of the hinge.

In the present organization the door is shown hung below the pivotal axes of the cranks with their hangers, whereupon when the door is'closed the crank-arms may be in a substantially perpendicular or dead -ccnter position and eectively maintain the door against opening movement. One of the cranks-as for instance, the crank 9-of each pair is provided with a crank-arm 15 for the attachment of door-actuating means, which in one form thereof comprises a pair of connecting-levers 1G and 16', each pivotally secured to a hanger adjacent to the lower end thereof, whereby such hangers constitute the with connecting-rods 17 and 17, secured to the crankarmsl The inner ends of these connecting-levers 16 and 16 are pivotally secured to an equalizer (shown as a member 1S) .pivotallyfsecured to aconnecting-rod 18', suitably guided bya guide 19, secnredto the door, the lower end of said rod being secured to an actuator, such as an angle-lever 20,\pivotally secured to the door and carryinga pawl 21 in operative engagement with a ratchet 22, fixed to the door. On shifting this angleleveras, for instance, to therright-it will be seen that the inner ends of the con meeting-levers 16 and 16' are drawn downward, thereby shifting the outer ends thereof upward to throw the crank-arms 15 outwardly and upwardly inthe arc ofa circle, whereby the door is shifted from its flush position obliquely or in two directions outwardly and upwardly, this l shifting movement being facilitated by beveling the door-lintel 23 and the upper edge of In the present.

,being sufficient to carry the the door 24. In the use of this equalizer 18 should one side of the d o'or in closin'gpmeet with an obstruction this device will act to preventthe breakage or strain of the actuating mechanism, since it is shiftable to operate one set of cranks while permitting the other set to remain inoperative, and is therefore an essential feature in an improvement in which considerable power is exerted.

Suitable means is provided to maintain the lower part of the door vin its iiush position with the door-case and also to maintain the same in its shifted position when the actuating means above set forth is operated, and in the present instance the door is provided on its inner side near its bottom with a fianged member, such asan L-shaped bar 25, a part of the ends of which project beyond the door, at each side thereof, such door being out away at this point for this purpose and the door-posts 26 also being cut away to provide a space for such L-shaped bar when the door is in its closed position iiush with the casing. l

Secured to the car-wall adjacent to each lower corner of the doorway is a bracket or stop 27, partly projecting into such doorway and provided with a beveled inner face 2S and adapted .to engage the ends of the L- shaped bar 25 of' the door when closed to prevent outward movement of such door, such beveled faces facilitating the shifting of the door outwardly and upwardly when the actuatingmechanismisoperated. Eachbracket 27 is provided with a flange 29, adapted to be engaged by the L-shaped bar 25 when the door is shifted outwardly and upwardly, (see dotted lines, Fig'. 6,)'such shifting movement, bar 25 of the door from its normal position back of such brackets into position to be engaged by the flange thereof, which4 movement may be assisted when necessary by pulling the lower end of the door outward during its movement. upward, which can be readily done by means of a handle 30, secured to the door.

In operation when it is desired to openthe door the pawl 21 is released from the ratchet 22 and the actuating-lever 2O thrown to the right, whereby the cranks are shifted into position to swing the door outward and upward from its flush position, Fig. 2, into the position shown in Fig. 3, in which position it is maintained by the, locking action of the pawl, the lower portion of the door being assisted in this movement when necessary by pulling the same outward by the handle 30. At this time the door is in position to be moved away from the doorway, which is ac- ICO complished by moving the same onn its track,

and lis 'electively andl a are olf their 'dead-centers or perpendicular positions and a're locked vagainst movementl bythe pawl-and-ra'tchet mechanism.

n When it is desired to close the car, the door is shifted from its position against the side of the car to permit it to run free on its track, and it is then moved into position opposite v the doorway, the bottom pushed inwardly suicient to permit the bar -v25 to engagethe beveled surface of the bracket 27, the pawl released from its ratchet, the actuating-lever 2O thrown to the left, thereby shifting the door'downward and inward into position flush with the door-casing, whereuponthe pawl acts toprevent the return movement of such actuator-lever.

In this improvem nt it will be seen that when the door is closed it is maintained shut by its own weight,'assisted by thecrank and actuating mechanisms, and that'when it is open it can be locked against movemen-t on g its track, and this without the use of an independent locking means or 'throwing the vtrack-rolls off the track.

-In the construction shown in Fig. 7 the door lis provided with only one doorcarrier, which in-this instance comprises a hanger 6', I located centrally of the door and providedA with a pair of track-engaging rolls 7' and 'a pair of depending meinbersB, by and intert mediate which apair of double cranks 36 are t supported, such cranks being secured to the j door by suitable plates-37. One of these cranks is provided with a crank-arm 38, to which'is secured a connecting-rod 18', the opposite end of which is secured to an actuator, l

such as an L-sh'aped lever 20', pivotally secured to the door and carrying a pawl 2l in engagement with a ratchet 22', also secu-redk to'the door. The movement of the door when this actuating mechanism is operated is substantially similar to that above set forth,ex cept that in this instance in order to open the door the lever is thrown to the left,'whereby the force exerted on the connecting-rod is in a direction coinciding with the movement of the door, whereas in the form shown in Fig.

I the force exerted-on the member 18' is in a direction opposite to the movement of the door. In this form, however, the bottom of the door is shownheld in its fiush position by brackets 27', thereby dispensing with the L- shaped bar, such brackets directly engaging the lower edge of the door lwhen in its shifted position;

'In practice the'door-lintel 23 is provided with a stop, such as a bar 40, to prevent'the d oorfrom being shifted beyond its `ilusl1^po-Y sitio'n, while the-outer wall of the car is provided with a stop 41 to limit the slid'ing'mo'vement of the Idoor. y

I desire to state that 'while the present organization is such that the door is vshifted from its #ush position into position for edgewise or sidewise movement on the outside of Ithe car, nevertheless it is to be understood that the same mechanism 'could be utilized by mere modification of details, soas to shift the door toward the interior of the car topermit Ithe same to slide4 on the inside thereofas, for instance, by some suitable means conlnected to the actuator 20 and projecting'ex- Fteriorly of the car-and therefore inthe speciication and claims it is to be understood that when the Worf outwardly for its equivalent is used it is not .to be'considered a limitation, since the door maybe moved inwardly as well as outwardly, as above' set forth. Moreover, Idesiretostate'that this improvement may 'be used in all kinds 'of freight box-cars, such as refrigerator-cars, duc., and'can,moreover, be used in connection with structures-other than' freight-cars, if desired, so that the term car-body or car structure as usedin the claims is not to be considered a limitation to structures of that class. y

In conclusion it will'be seen that the dooractuating means comprises a crank-and-lever system which owing to its organization is efv fective to exert a powerful leverage upon the door, while requiring com para-tivel y-little ef- Ifort to operate the same. v

vBy'the provision of a-carrier'einbodying a pair or more of cranks it will be seen that the door has '-a steady parallel motion, thus avoiding the swinging movement which might be 'present if the carrier embodied only one crank, and thatl by the provision of a door in which the supporting mechanism therefor is above the door all damage thereto is avoided by the backing of wagons against the car, as would be the case were `such mechanism located at the bottom orsides of the door. Moreover, whenthe door is shiftable outwardly weight, and the tendency of the door is to remain shut, which is ,not the case when the door is supported at the bottom or sides or when it is movable outwardly and downwardly. Furthermore, when freight becomes displaced or has fallenl against the door such door can be more readily moved -upwardly than moved downwardly, sinceY such down- :ward movement tends to increasethe binding effect of the displaced freight, as the .cariioorwill prevent all movement of the freight with the door. In practice it is frequently necessary to cut into the d'oorin' order-to'get at the freight to release it Vfrom its binding .position against the door, into which position it has fallen, and this binding eect is over'- come by moving the door upwardly,since such upward movement acts to carry the vsufficiently to enable the door to be4 opened,
